If you’ve ever seen an old metal roof, it might be covered with rust. This is not only unattractive but also alarming if you’re thinking about investing in this type of roof. If rust takes over a metal roof, it can destroy it. The good news is that modern metal roofs don’t have this problem. Here’s what prevents metal roofs from rusting or corroding. 

What Prevents Metal Roofs from Rusting?

Rust on a metal roof is something you want to avoid. If you have an older metal roof with rust, you either need to have the rust removed or consider replacing your roof. But rust and corrosion never have to happen with this type of roof. Here are several solutions for preventing metal roofs from rusting. 

Roof Coatings

One great way to prevent rust and corrosion is with elastomeric coatings. This is a metal roof sealing system made from acrylic that is applied in layers. The coating creates a barrier that is incredibly effective against corrosion and rust. It’s vital that the roof is clean before the coating is applied. Also, the coatings come in a variety of colors. 

High-Quality Metal Roof Panels

If you want to avoid rust and corrosion, it’s essential to use only high-quality roofing panels. It’s also vital that your panels contain zinc, which is a material that protects the cut edges of the panels from exposure. If you use low-quality metal roof materials, those cut edges can expose the metal to the elements and invite rust. 

Metal Roof Paint

Another way to get zinc onto your metal roofing panels is with the right kind of paint job. Specifically, a primer that contains at least 80% of zinc is a great rust-prevention material. Similar to roof coatings, a metal roof must be cleaned and prepared before painting to achieve the best possible results. 

Galvanized Roofing

Zinc also comes into play with galvanized roofing, which is known to be rust-proof material. To create galvanized metal, a roof will need to be treated with liquified zinc. Because the zinc creates a protective layer on the metal panels, this safeguards it from rust and extends its longevity.
